Abstract

The invention discloses a kind of plug valve of structure optimization, including valve body, the valve inner includes flap, valve rod, filler pressing sleeve, hold-down grid, support, gear-box, handle and bonnet, it is bolted between the bonnet and valve body and support, the gear-box is used for band ovable valve stem and moved up and down, handle opens and closes for control valve, the filler pressing sleeve coordinated with valve rod is additionally provided with the bonnet, the upper end of filler pressing sleeve is also equipped with hold-down grid.For the present invention by arranging stiffening ring, reinforcing rib structure in plug valve outer wall, very high stress concentration can be produced by solving valve body tapping (passage), the problem of making sealing surface generation moderate finite deformation and cause sealing leak.

Description

A kind of plug valve of structure optimization
Technical field
The present invention relates to technical field of valve manufacturing, it is specifically a kind of applied to oilfield exploitation, oil and natural gas it is defeated Send pipe network, the plug valve of structure optimization in refining equipment field.
Background technology
Plug valve is widely used in oilfield exploitation, conveying and concise equipment, while is also widely used in petrochemical industry, is changed In work, coal gas, natural gas, liquefied petroleum gas, HVAC industry and general industry.Plug valve is usually used in corrosivity, severe toxicity and height The severe rugged environments such as medium are endangered, the strict occasion for prohibiting leakage, and valve material will not form the occasion of pollution to medium.Cock Valve body is three-port structure, lumen is regarded as supervisor, runner is considered as branch pipe.Valve body tapping (passage) can produce very high stress Concentrate, sealing surface is produced moderate finite deformation and is caused sealing leak.Therefore, in order to reduce stress concentration and excessive deformation, ability Field technique personnel propose a kind of plug valve of structure optimization, to solve the problems mentioned in the above background technology.
The content of the invention
It is an object of the invention to provide a kind of plug valve of structure optimization, is asked with solve to propose in above-mentioned background technology Topic.
To achieve the above object, the present invention provides following technical scheme:
A kind of plug valve of structure optimization, including valve body, the valve inner include flap, valve rod, filler pressing sleeve, filler Pressing plate, support, gear-box, handle and bonnet, it is bolted between the bonnet and valve body and support, outside the valve body Wall cloth is equipped with stiffening ring, and the gear-box is used for band ovable valve stem and moved up and down, and handle opens and closes for control valve, described The filler pressing sleeve coordinated with valve rod is additionally provided with bonnet, the upper end of filler pressing sleeve is also equipped with hold-down grid, the flap and valve Body sealing surface uses conical surface seal.
As the further scheme of the present invention:Connected between the flap and valve rod using T-shape slot.
Compared with prior art, the beneficial effects of the invention are as follows:By arranging stiffening ring, reinforcement knot in plug valve outer wall Structure, very high stress concentration can be produced by solving valve body tapping (passage), sealing surface is produced moderate finite deformation and is caused to seal The problem of leakage.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is that valve outer wall of the present invention arranges stiffening ring schematic diagram.
In figure:1- valve bodies, 2- flaps, 3- valve rods, 4- filler pressing sleeves, 5- hold-down grids, 6- supports, 7- gear-boxes, 8- hands Handle, 9- bonnets, 10- stiffening rings.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made Embodiment, belong to the scope of protection of the invention.
Refer to Fig. 1-2, in the embodiment of the present invention, a kind of plug valve of structure optimization, including valve body 1, in the valve body 1 Portion includes flap 2, valve rod 3, filler pressing sleeve 4, hold-down grid 5, support 6, gear-box 7, handle 8 and bonnet 9, the bonnet 9 with It is bolted between valve body 1 and support 6, the gear-box 7 is used for band ovable valve stem 3 and moved up and down, and handle 8 is used to control Valve opening and closing, connected between the flap 2 and valve rod 3 using T-shape slot, be additionally provided with the bonnet 9 and match somebody with somebody with valve rod 3 The filler pressing sleeve 4 of conjunction, the upper end of filler pressing sleeve 4 are also equipped with hold-down grid 5.
In the present embodiment, it is close using the conical surface that the outer wall of valve body 1 is disposed with stiffening ring 10, flap 2 and the sealing surface of valve body 1 Seal, flap 2 is increasing to the power of the tapping of valve body 1 (passage) in closing process, and the outer wall of valve body 1 arrangement stiffening ring 10 can be protected Demonstrate,prove the intensity of valve body 1 and reduce tapping (passage) stress concentration and sealing facial disfigurement, it is met intensity requirement and deformation respectively Condition, to ensure the security of valve and sealing property.
The plug valve of the structure optimization, flap 2 and valve rod 3 are placed in valve body 1, and flap 2 and the sealing surface of valve body 1 use the conical surface Sealing, flap 2 are connected using T-shape slot with valve rod 3, moved up and down by gear-box 7 with ovable valve stem 3, operation handle 8 can be controlled Valve opening processed and closing, the outer wall of valve body 1 arrangement stiffening ring 10, it is ensured that valve when closed open by the intensity of valve body 1 and reduction (passage) stress concentration and sealing facial disfigurement, make it meet intensity requirement and deformation condition respectively, to ensure the peace of valve at hole Full property and sealing property.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, not On the premise of departing from present inventive concept, several modifications and improvements can also be made, these should also be considered as the protection model of the present invention Enclose, these effects and practical applicability for implementing all without the influence present invention.
